Kunstwerk Carlshütte, a non-profit initiative of the ACO Group, and the towns of Büdelsdorf and Rendsburg, organises the NordArt, an annual international exhibition of visual arts from June to the beginning of October. The art exhibited at NordArt is selected by a jury and features all visual art media.

Since 1999 the NordArt has established itself as one of the largest exhibitions of contemporary art in Europe which takes place anually in the summer months. The NordArt is an overall work of art in its own right and is designed as such each year. More than 200 international artists present a comprehensive panorama of contemporary art. Each individual work not only speaks for itself but also creates new perspectives when seen juxtaposed against the unique backdrop offered by the Carlshütte and the adjacent historical sculpture park.

The exhibition also features the highly respected NordArt Symposium, bringing together different generations of artists from around the world to engage in debate, make new acquaintances, and work. The results are then displayed in the Carlshütte and the sculpture park.
